There's a lot media noise about the shoot-down of the American Chinook helicopter that killed the barely mentioned yet just as dead Afghan soldiers and the always mentioned US Navy special forces (SEALS) who were all on board. [Odd how the locals usually rate a secondary mention compared to NATO glory-units. Tells you something about who this war is really for. I digress.]
BBC reports the US line being this is a "one-off" as if it some sort of a rarity over there. This isn't true.
There's a Wikipedia page that tracks aircraft losses in Afghanistan. If you read through it, Canada has actually lost two Chinooks (of six) and a Griffon, including one of the former confirmed as shot-down. Total helicopter losses to date are 101, and fixed wing 23. Most are lost to accident but it makes no difference to the dead, wounded, and bean-counters whether they were lost to enemy action or simply Afghanistan. It's the mission that wrecked them.
A minor point maybe, but it helps clear a way a little of the whaleshit military PR people, politicians, and some of their media parrots pump around events like this.
